Keunggulan Teknis Inti
-
Process Isolation: The switching mechanism is completely isolated from the process fluid via a corrosion-resistant torque tube assembly. This eliminates the need for dynamic seals that could leak, significantly increasing long-term reliability.
-
NACE Compliance: Standard constructions are available to meet NACE MR0175-2002 requirements, making them suitable for sour oil and gas applications where H2S is present.
-
Flexible Mounting and Piping: The displacer cage features two 1-inch NPT pipe plugs that can be relocated to accommodate either horizontal or vertical equalizing piping. Additionally, the switch itself can be ordered in left-hand or right-hand mounting configurations to fit tight skid spaces.
-
Field-Reversible Action: The switching logic is easily reversible in the field. You can switch from high-level trip to low-level trip (or vice versa) without needing to purchase any additional parts or conversion kits.
-
Electric Retrofit Capability: The 2100E features an explosion-proof, hermetically sealed electric switch. This module can be factory-installed or purchased as a retrofit kit to convert existing pneumatic 2100 units to electric operation.
